1 IU vitamin A Palmitate = 0.55 mcg
Ex:
100 IU vitamin A Palmitate = 55 mcg
ie multiply the IU by 0.55
how can convert 100 mcg B12 in mg
30.12 mgFom IU to mcg: 50000 IU/1.66 = 30120 mcgFrom mcg to mg: 30120 mcg/1000 = 30.12 mg Final AnswerFrom USDATo convert Vitamin A as beta-carotene:From IU to mcg: IU/1.66 = mcgFrom mcg to IU: mcg * 1.66 = IUSource http://dietarysupplementdatabase.usda.nih.gov/ingredient_calculator/help.php#q2Ther are 1000 mcg in a mg so to convert to miligrams you have to divide the micograms by 1000.
To convert 1000 mcg to IU, the specific conversion factor depends on the substance being converted. For example, for vitamin A, the conversion factor is often 3.33 IU per mcg. To find the equivalent IU value, you would multiply 1000 mcg by the conversion factor.
1000 mcg per 100 IU
Keep in mind that conversions from IU to mg are specific for each vitamin, so this formula/answer is only applicable for Vitamin D. You first have to convert the 2,000 IU into mcg. Each IU of Vitamin D is equal to 40 mcg, so you divide 2,000 by 40 which equals 50. Then you have to convert the mcg amount into mg which you do by dividing the mcg amount by 100. In this case 50 divided by 100, which equals 0.5, which means that 2,000 IU of Vitamin D is 0.5 mg
an IU is not a standardized unit that can be converted to mg with a single formula. IUs means something different for each item (usually vitamins) it is used for. So for one vitamin you could have 1000IUs and it is 10mg, whereas 10mg of another vitamin is only 100IU.
10,000 IU of vitamin A is equivalent to 3,000 mcg.
1 mcg vitamin D (cholecalciferol) = 40 IU Let´s say you have 300 IU of vitamin D: 300 / 40 = 7,5 mcg vit. D Then you would have to convert 7,5 mcg to mg: 7,5 / 1000 = 0,0075 mg vitamin D.
3500 IU is equal to 1050 mcg (microgram) retinol (Vitamin A)
To convert the units, it's important to know that 1 microgram (mcg) of vitamin B12 is equivalent to approximately 40 International Units (IU). Therefore, to equal 2.4 mcg of B12, you would need about 96 IU (2.4 mcg x 40 IU/mcg). Since 1000 IU is much larger than 96 IU, 1000 IU of B12 is far more than needed to meet the 2.4 mcg requirement.
An International Unit (IU) is a standardized measurement used to quantify vitamins A, D, and E. The conversion to micrograms (mcg) or milligrams (mg) varies for each vitamin. For vitamin A, 1 IU is equivalent to 0.3 mcg retinol. For vitamin D, 1 IU is equivalent to 0.025 mcg cholecalciferol. For vitamin E, 1 IU is equivalent to 0.67 mg tocopherol.
